According to Kent Bach (forthcoming), our book, Insensitive Semantics (IS), suffers from its 'implicit endorsement' of (1): (1) Every complete sentence expresses a proposition (this is Propositionalism, a fancy version of the old grammar school dictum that every complete sentence expresses a complete thought) (Bach (ms.)) In response (C&L, forthcoming), we claim to be unaware of endorsing (1). No argument in IS depends on (1), we say. We don't claim to have shown that that there couldn't be grammatical sentences the semantic contents of which are not propositional.
